jquerized

  * Fix selector in subtree loading callback
  * Remove HTML inconsistencies between AJAX and plain PHP lists
  * Unify icon and CSS class switching in dw_tree and dw_mediamanager

Make it faster, prettier, less wrong, add UI effects, use jQuery UI Dialog,
Abstract tree view stuff away into jQuery.dw_tree

There are probably more functions that should go in here

  * Increase HTTP cache time since the resources are timestamped on request
    anyway
  * Check userscript.js only once for JS cache validation
  * Use cache class

  * Move file to qsearch.js
  * Rename object to dw_qsearch
  * Remove unnecessary usage of Delay
  * Use $ prefix for jQuery objects
  * Fix result list hiding on click
  * Fix namespace shorting

  * Removed "use strict" statement, since it does not work with our script file
    joining (the statement has to be the first in a file or function)
  * Make index a global object again to allow overriding and enhancing
  * Use prefix dw_ for index object
  * Reintroduce index.treeattach
  * Support deprecated index.toggle calling convention
  * Add $ prefix for jQuery variables
  * Use slide animation for freshly loaded sublists as well
  * Fix various errors

The feature is now disabled by default.
Metadata for config manager was added.

This patch adds a new config option 'cssdatauri'. When enabled, the CSS
patcher will automatically convert all occurances of small (<600 byte)
PNG and GIF images in the CSS to embedded, base64 encoded data uris.

This reduces the number of needed HTTP requests and avoids the HTTP header
overhead.

JavaScript functions adding behaviours based on IDs or class names where
moved to their own object into behaviour.js and where jQueryized.

This fixes a problem with running the minified jQuery through the
compressor.

This patch adds a simple shell script to easily update the
jQuery/jQuery-UI+theme bundle to the latest available version.

The jQuery-UI CSS theme is now loaded in lib/exe/css.php (before plugin
and template styles - 3rd party authors can override the styles).

This avoids problems when the files are concatenated later.

The security token here doesn't improve the security as the other
requests that allow you to do the same thing aren't protected and I
don't see why locking or draft creation should be subject of XSRF
attacks.

This disables lock and draft creation for pages the user can't edit. It
additionally adds a security token to the draft creation and deletion
request so - at least for logged in users - drafts can't be created,
modified or deleted so easily anymore.

If no HTML element with the id wiki__text exists, locktimer.init led to a
JavaScript error.

Make interwiki links match with every other icon-link: need 1px top and bottom padding or else the icons' top and bottom pixel rows get cut off.

* code cleanup in lib/exe/css.php
* renamed 'default' userstyle to 'screen' in config_cascade
* splitted core lib/styles/style.css up into all.css, print.css and screen.css

Previously the rmdir could be executed when the lock directory had been
deleted by another indexer already. This could lead to a race condition
when another indexer call creates the lock again between the if and the
rmdir. This issue still exists for stale lock directories but they
normally shouldn't exist.
This also prevents the loop from becoming an endless loop when the lock
directory can't be created.
This change also fixes a syntax error in the indexer and prevents an
endless loop when the lock directory exists but can't be deleted.

Changes:
  * XML-RPC now correctly allows leading and trailing _
  * Error messages from XML-RPC are correct
  * MEDIA_UPLOAD_FINISH has a sixth param specifying the move function
  * Not having upload rights when using media_upload throws a msg

Functionality changes:
  * deleteAttachment now triggers MEDIA_DELETE_FILE (closes FS#1568)
  * deletion success msg in mediamanager is correct, even when the ns dir
    was deleted
  * media_delete changed quite a bit
